Specification of Letters Patent.

Patented Apr. 28, 1914.

Application filed. March 21, 1910. Serial No. 550,681.

To all .0710122 it may concern:

Be it known that I, BERT RIVKIN, a citizen of the United States, and aresident of New York, borough of Bronx, inthe county of New York andState of New York, have invented certain new and useful Improvements inl Vindow-Shade Rollers, of which the following is a specification.

The objects of this invention are to provide a new and simple means forcontrolling the operation of a window shade, whereby the shade may beoperated entirely inclependent of itself and thereby greatly increasethe life of the shade, also to prevent the soiling of the same byhandling, and to prevent the unrolling of the shade by the breeze whenthe window is left open and the shade is allowed to blow back and forth.

The further objects are to provide an attachment which is simple andinexpensive to manufacture, and which does not need to be adjusted, andwill not get out of order, and will hold the shade in any desiredposition, and to also provide a fixture which will not allow the shaderoller to slip out of its sockets and be pulled down when the shade isbeing raised or lowered.

The foregoing features will be clearly seen by referring to the drawingforming a part of this specification, of which- Figure 1 is aperspective view of my invention; Fig. 2 is an enlarged detailperspective view; Fig. 3 is an enlarged longitudinal section, showingthe arrangement of the several parts; Fig. 4 is a transverse section online mw of Fig. 3; Fig. 5 is a detail perspective view of one sideplate; Fig. 6 is a similar view of the other side plate; Figs. 7 and 8are detail perspectives of the spring or friction device; Fig. 9 is oneof the journals which forms a drum; Fig. 10 is one of the guides orsides of the drum; Fig. 11 is a perspective view of one of the journals;Fig. 12 is a longitudinal section of a modification of my invention;Figs. 13 and 14 are perspective views of the side plates and the guideor hood which forms the bracket shown in Fig. 12; Fig. 15 is aperspective view of the spring used in Fig. 12; and Figs. 16 and 17 area modification of the journal and end plate for the shade, which may beused in place of the journal shown in Fig. 9; Fig. 18 is a section ofone end of a shade roller showing means for preventing the roller fromsplitting, and is used when the shade is very large or heavy.

It will be seen by referring to the drawings that I h ave provided asimple and ef fective shade roller, which consists of the ordinarywooden roller 2, to which the shade 2' is attached by any suitablemeans, having journals 3 and 42 which have enlarged outer ends 5, whichprevent the journals from being drawn out of their bearings and thuskeep all of the parts assembled after the flattened and tapering ends 6have been driven into the roller 2.

By referring to Fig. 8, it will be seen that the journal 3 has a longbody portion 8. This is to allow for adjusting the side plates 9 and 10to the window frame, as indicated by dotted lines. Tris adjustabilityhas been found very advantageous, owing to the warp of the wood and theunevenness in the building of window frames, and it overcomes a greatannoyance due to the swelling and shrinkage of the wood in various kindsof weather, which causes the rollers now in use not to work in dampweather and to fall from their bearings in dry weather. These annoyancesare overcome by the self adjusting feature of this bearing.

The journal 4 is provided with a hole 11 through which is passed andsecured a cord or cable 12, a suflicient portion of which has been woundon the journal to equal the length of the shade and also in the samedirection as the shade is wound on the roller 2. The cord 12 is allowedto hang in the form of a loop within easy reaching distance, and theother end is passed through the hole 11 in the opposite direction to thefirst end and secured in any suitable manner. The journal 4: is furtherprovided with a pair of guide plates 13 and 14C for guiding the rollingup of the cord or cable 12, and, if desired, for cheapening themanufacture of the device, the guide plates may have a hole 15 punchedin them for the reception of the ends of the cord or cable 12 instead ofthe hole 11 in the journal. If this is done one end of the cord 12 willbe secured in the guide plate 13 and then the cord wound on the journalthe same as before described and the other end secured to the guideplate 1 The side plate is provided with an elongated opening 16, whichis at an angle of about 45 degrees to its perpendicular axis. The upperend of this slot or opening terminates in an enlargement 17 the lowerend of which passes around the corner and then downwardly or parallelwith the perpendicular axis of the side plate, forming a side opening18. This opening 18 is to allow the locking members 19 and 20 of thefriction spring 21 to be passed into position. The friction spring 21 isprovided with a pair of downwardly extending ears 22 which overlap theoutside of the guide plates 13 and 14, and these ears 22 prevent thespring 21 from becoming misplaced. The spring 21 is made so as to have afirm bearing upon the periphery of the side guides, and this frictioncauses the roller to be locked in any position that is desired. Thespring 21 is held. in position by having its locking lugs passed throughthe opening 18, and the body 21' being passed into the slot 16, thespring is then drawn forward until the lug 19 presses against the insideof the side plate 10 and the lug 20 is locatedin the enlargement 17. Itwill thus be seen that the lug 20 prevents the spring from being drawnout of the slot in one direction and that the lug 19 prevents it frombeing drawn out in the other direction. The upward pressure caused bythe side guides 13 and 14: of the journal, and the ears 22 of the springprevent it from being pushed back in the slot and becoming loose. Itwill thus be seen that all the parts of the device interlock with eachother after being assembled, without the aid of bolts, screws, rivets orsolder, which are the expensive parts of manufacturing.

The side plates 9 and 10 are provided with openings 23 for the receptionof ordinary wood screws 24- to fasten them to the window frame, and arefurther provided with a boss 25 which forms an extension bearing for thejournals to allow for the variation in the window frames.

By referring to Figs. 12, 13 and 1 1, in which I have shown amodification, it will be seen that I have providedthe side plate with anextension guide 26, which, taken in connection with the side plate 27,takes the place of the guide plates 13 and 1 1 to insure the properwinding of the cord or cable 12. The side plate 27 is also provided withtwo partial perforations 28, and the metal which is forced out of theseperforations is formed into tongues 29 which are so bent as to form aslot 30 between the inner surfaces of the plates 27 and their outersurfaces. This slot 30 takes the place of the slot 16 for the purpose ofmaintaining the spring 31, which is bent atthe top forming a lockingportion 82.

It will be noted that in this cmislruclion the spring 31 bears directlyon the end of the journal 4. instead of on the guide plates. Thefriction is thus caused by the enlarged end 5 of the journal beingpressed against the bearing 86, and also the pressure of the spring onthe end of the journal, but the function is the same as in the devicebefore described.

The guide 26 of the side plate 27, which is shown in the form of apartial hood with an opening 33 in the bottom for the cord or cable 12to pass through, may also be, if dcsired, made a complete hood orhousing without affecting the operation of the device as long as it hasthe opening 33 in it. This guide 26 may be made integral with the sideplate, or, as I have shown it, with the side plate, having openings orslots 31: for the reception of tongues of the guide or hood, which whenpassed through the slots 31 are upset or bent over to hold the guidewedged in its pro-per position.

Fig 1G is a modification of the journal I, the difference being in theend portion 37, which is made square in section and to it the opening 38of the plate shown in Fig. 17. This plate or dish is provided with n plurality of countersunk holes 40 for wood screws to fasten the same tothe end of the roller 2; and if desired this plate 39 may be made in theform of a cap, that is to have a flange to fit over the end of theroller 2, as shown in Fig. 18, to prevent the same from splitting. Thisform of journal and end protection for the roller 2 is used in cases ofvery large shade rollers such as are used in display windows of stores.

It will be seen by the foregoing description that many similarmodifications may be made to facilitate the manufacture of these devicesand to meet the demands of the various situations and designs of windowframes without departing from the spirit of my invent-ion, and I wish toreserve such rights to make any necessary changes.

The operation of this device is extremely simple. After the shade hasbeen placed in position, by pulling on the cord 12 which is wound on thejournal, it will cause the roller to revolve and unwind the shade, andat the same time cause the exact amount of the other end of the cord towind up in the opposite direction on the ournal as has been unwound bythe pulling of the cord. It will thus be seen that by pulling on eitherone side or the other of the loop 11 the shade may be either rolled upor unrolled, as desired by the operator, without touching the shadeitself, and the friction spring will hold the shade securely in anyposition in which it is left.

I claim as my invention:

1. A window shade having elongated journals, one of which acts as adrum, a side plate, a hood mounted upon the side plate, the side plateand hood having bearings for the journal and acting as guides for thecord or cable wound upon the journal for rotating the roller in eitherdirection, and means for holding the shade or roller in any position.

2. A window shade having a roller with elongated journals, one of whichacts in the capacity of a drum, a side plate in the form of a bracketand acting as a guide for the cord or cable which is wound upon thejournal, and capable of rotating the roller in either direction, meansfor holding the shade at any desired height, and an automatic adjustingbearing, the adj ustability being in line with its axis and movableinclependently of the holding or operating means of the roller.

3. A window shade having a roller with elongated journals, one of whichacts in the capacity of a drum, a side plate in the form of a bracketand acting as a guide for the cord or cable which is wound upon thejournal and capable of rotating the roller in either direction, meansfor holding the shade at any desired height, a. second side plate withan extended bearing which acts with one of the elongated journals andcompensates for the varying widths of windows, and an automaticadjusting bearing, the adjustability being in line with its axis andmovable independently of the holding or operating means of the roller.

4-. A window shade, having elongated journals, one of which acts as adrum, a side plate, a hood mounted upon the side plate, the side plateand hood having bearings for the journal and acting as guides for thecord or cable wound upon the journal for rotating the roller in eitherdirection, means for holdingthe shade or roller in any position, aself-adjusting bearing, the adjustability being in line with its axisand movable independently of the holding or operating means of theroller, and means for keeping all the parts assembled upon the rollerwhen the shades are being transported.
